Abstract. The species richness and species composition of bryophytes (mosses and liverworts) was recorded at
33 sites in Tasmanian old growth mixed eucalypt forest. A total of 202 bryophyte taxa were recorded, consisting of
115 liverworts and 87 mosses. This constitutes approximately one third of the total bryophyte flora for Tasmania.
Mean liverwort species richness per site was higher than moss species richness. Latitude was found to be a
positive predictor in all multiple regression models of bryophyte, moss and liverwort species richness. Mean annual
temperature and rainfall of the driest month were positive predictors for bryophyte and liverwort species richness.
Basal area of the treefern Dicksonia antarctica Labill.was a negative predictor of liverwort species richness. Latitude,
variables relating to moisture, mean annual temperature, rainfall of the driest month and basal area of Dicksonia
antarctica were the most significant components in predicting variation in bryophyte, moss and liverwort species
composition. There were few relationships between the variables of canopy cover and soil nutrients and bryophyte
species richness and composition. Substrate variableswere found to be important components in predicting variation
in moss and bryophyte species composition.
